# Difference of Squares Welcome to Difference of Squares on Exercism's Rust Track. If you need help running the tests or submitting your code, check out `HELP.md`. ## Instructions Find the difference between the square of the sum and the sum of the squares of the first N natural numbers. The square of the sum of the first ten natural numbers is (1 + 2 + ... + 10)² = 55² = 3025. The sum of the squares of the first ten natural numbers is 1² + 2² + ... + 10² = 385. Hence the difference between the square of the sum of the first ten natural numbers and the sum of the squares of the first ten natural numbers is 3025 - 385 = 2640. You are not expected to discover an efficient solution to this yourself from first principles; research is allowed, indeed, encouraged. Finding the best algorithm for the problem is a key skill in software engineering. ## Source ### Created by - @EduardoBautista ### Contributed to by - @ashleygwilliams - @coriolinus - @cwhakes - @eddyp - @EduardoBautista - @efx - @ErikSchierboom - @IanWhitney - @kytrinyx - @leoyvens - @lutostag - @mkantor - @nfiles - @petertseng - @rofrol - @stringparser - @TheDarkula - @xakon - @ZapAnton ### Based on Problem 6 at Project Euler - https://projecteuler.net/problem=6
